Hi, I have created a database using VWD to keep values of urls and have structured it as... Prefix (http://, network name), address(www.name.com), and name (name of address), the address field has been defined as a nvarchar(MAX). Most of the addresses updated into the address field work, except something like: www.java-scripts.net/javascripts/Image-Rollover-Script.phtml. I get this error: Cannot open user default database. Login failed.Login failed for user 'NETWORKNAMEASPNET'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.SqlClient.SqlException: Cannot open user default database. Login failed.Login failed for user 'NETWORKNAMEASPNET'.Source Error:

Any ideas why?If it is a nvarchar type it should be able to except all sorts of characters??
Hi there,I have a table named Action. This table has a column InPrice with datatypenvarchar(12). I want to change its datatype from nvarchar(12) to money. Ibrowsed through the values and removed any dots. Th column now has onlynumeric values (and commas for decimal values such as 105,8). When I try tochange the datatype from nvarchar to money, following mesage is displayed:ADO error: Cannot convert a char value to money. The char value hasincorrect syntax.How can I solve this problem? I cannot figure out which values are causingthis error.Thanks in advance,Burak
We have few stored procedures that use nvarchar datatype, this was not issue on SQL server 7.0 but in 2000 becomes a big issue. For example query that runs for 3 minutes in SQL server 2000 by replacing NVARCHAR to VARCHAR the same query runs for 2 seconds. The biggest challenge that I have deals with tables and user-defined datatypes of NVARCHAR that has been bounded to the table. How can I alter those without data corruption?
I am facing a problem while using SQL Server with VB application.Implicit conversion from datatype text to nvarchar is not allowed.Use the convert function to run this query.When i see the trace file, i see one stored procedure called but nolines of code get executed, and immediately after that the ROLLBACKTRANSACTION occurs and the applications fails.But to my surprise i am able to do the same thing on a differentmachine using the same application and the same database on the sameserver with the same user id.Can anyone explain the reason of occurance of this problem.I require this very urgently, so i will be oblized if anyone can comeup with a quick response.Kind Regards,Amit Kumar
I am updating a remote table using linked server in sql server 2005.
but in case of varchar and nvarchar i am getting an error : "OLE DB provider "SQLNCLI" for linked server "LinkedServer1" returned message "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.". Msg 16955, Level 16, State 2, Line 1 Could not create an acceptable cursor."
Hi All: I am new to Sql 2000 database,Now I'm planing to create a table in my databse,my table included below fields like this : PoNo(the length is 15 characters) ,Supplier Name(the length is 50 characters).etc but I don't how to select the datatype for them. should I select Char or VarChar ? which one is the best slection ? thans in advanced!
Ok I have upgraded my works database from a poorly designed Access database to a SQL database. The previous system allowed NULL values and duplicates to be inserted into a field that should NOT ALLOW NULL Values or duplicates. Therefore, this issue has now been moved across to my new system as I cannot set these constraints on the field that has multiple NULL values.
My solution would be to use a sequential operator, so whatever = NULL would be changed to a sequential number that us as administrators would know was a bogus number starting at something like = 999999900 counting up from that. There are only 250 records that would require updating.
To make things more interesting this field is not a integer type, its a Nvarchar type as its a Hardware ID. Both numerical and characters are require.
insert into scn_transaction (sourceSystemName) values(@sourceSystem);
SELECT @txOut = @@identity
Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).
I execute the stored proc with the following sql with an OLE DB connection manager:
exec sp_newTransaction ?, ?
The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:
The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.
At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.
I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.

I have a field in a table that stores date of birth. The field's datatype is char(6) and looks like this: 091703 (mmddyy). I want to convert this value to a datetime datatype.
What is the syntax to convert char(6) to datetime?
HI,I have a table with IDENTITY column with the datatype as INTEGER. Nowthis table record count is almost reaching its limt. that is totalrecord count is almost near to 2^31-1. It will reach the limit with inanother one or two months.In order to avoid the arithmentic overflow error 8115, we would likechange the datatype from INT to BIGINT. we hope this will solve ourproblem.How do I approch this datatype conversion?. Since the data count ishuge, that leads to a long down time of database.we need better approach or solution for this problem?. kindly give mea better solution that will reduce the total downtime of the productiondatabase.?.Regards
I have a column that is a currently set as nvarchar(50) and is called DateEmployed. There are over a hundred rows that contain dates which is in nvarchar format.
This column now needs to be changed to a DateTime datatype. (Don't ask me it was not set to a dateTime when this was first designed - I wasn't here)
However, I have to change this column to a DateTime without destroying the data.
Is there any easy way to write some script or use studio management to change this.
Currently the data is displayed like this in this column dd/MM/yyyy i.e. 25/8/2007.
The method I am using to try and change this is by going to studio management clicking modify on the column and changing the datatype from a nvarchar(50) to a DateTime.
I get this following error message: - Unable to modify table. Arithmetic overflow error converting expression to data type datetime. The statement has been terminated.
I have a USERS database table with a column called IsValidated. It identifies if a user has been validated. I'd like to know which datatype would be the most efficient for this column. Our DBA made it a varchar(1) column. Would using int be better? Please advice.
I have a message box or multiline textbox on my form and I am storing into an SQL DB. I currently have it as a VARCHAR, but that doesn't seem to store the carriage returns. Do I have to store them as a nvarchar, text, ntext or something else to make the returns show? I am pulling them out of the DB and showing them in a label where I replace the with a <br>.

Over the years I have always used the decimal(18,0) as the datatype forprimary keys. Aside from the number of significant numbers involved,would BigInt type be better for performance or is decimal(18,0) still okay.--Don VaillancourtDirector of Software DevelopmentWEB IMPACT INC.phone: 416-815-2000 ext. 245fax: 416-815-2001email: Join Bytes! <mailto:donv@webimpact.com>web: http://www.web-impact.comWeb Impact Inc. <http://www.web-impact.com>This email message is intended only for the addressee(s) and containsinformation that may be confidential and/or copyright.If you are not the intended recipient please notify the sender by replyemail and immediately delete this email.Use, disclosure or reproduction of this email by anyone other than theintended recipient(s) is strictly prohibited.
